rI hisv invention relates to a. gang mold Vdesigned primarily `for molding concrete fence posts, but it is to vloe understood that a mold in accordancenrith` this intention may be em- 5' ployed in any connection for which it may be found applicable, and the invention has for its object to provide, ina manner as hereinafter set forth a mold of the class referred to-for expeditiously molding simultaneously a series i of apertured, reinforced concrete fence posts and so constructed andy arranged to. enable vthe quick discharge therefrom ofv the molded posts when occasion requires.

A further object of the `invention is to pro- \l5. vide,.in a manner. as hereinafter set forth a gang mold for molding at one time a series of apertured, reinforced'concrete fence posts, and with the elements of the mold so constructed as to permit the quick assembling andfdiswassembling of the latter when desired. l y l Further objects of the invention are to provide, in a manner las hereinafter set.. forth a` 30 view the invention consists o f the novel construction, combinationand arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it isvto be understood Y Vthat changes,- variations and modifications can be resorted to which fall withi-nthe scope of the claims hereunto appended.

Figure 6 is a fragmentary View in elevation of the upper portion of the molded post with a fence wire anchored thereto.

Figure 7 is a sectional plan of the molded post illustrating a fence wire anchored thereto.

A gang mold. in accordance with this invention includes a pair of oppositely disposed angle-shape upper holders 1, 2 and each of which consists of a vertical flange 3 and a horizontal flange 4' extendingoutwardly at right angles to the bottom of flange 3. The length of each holder is slightly greater than the number of molding units constituting the gang,and as illustrated by way of example, eleven molding units are employed to provide. the gang, the latter consisting of a central or inner molding unit, two sets of intermediate molding units .and a pair of outer or endmolding units. Each set is arranged between an outer and the central unit. The outer units are indicated 5, 6,' the units of one set 7, 8 and 9, the central unit 10 and the units of the other set at 11, 12 and 13. The holders are positioned at the ends of the units. The units of the gang are arranged in sidewise opposed` relation.

The mold also includes a pair of oppositely disposed angle shape lower holders 14, 15 and each of which consists of a vertical ange 16 and a horizontal flange 17 extending inwardly from the upper end of flange 16. The lower holders .are of slightly less length than the upper holders, but project beyond theouter molding units 5, 6.

The upper. holders are positioned at the top of the molding units at opposite ends of the latter. The lower holders are at the bottom of the molding units and at opposite ends ofthe latter. The lower holders are inset with respect to the upper carriers. The flanges of the lower holders are of less width than that 95 of the upper holders. Secured to the inner face of each upper holder are spaced supporting blocks 18 for seating on the upper carriers of al lower gang mold when the moldsare stacked during the curing period for the 100 37.0` the'heads 25 and the head 26-has a seniaredA` 1Lrfninterrupted inner face29.
